As the urban population increases, human requirements for structural buildings continue to increase. The development of new building materials is a major requirement for the country to implement innovation-driven strategies and new urbanization development goals. It is an inevitable choice for the construction industry to realize the transformation of economic development methods and sustainable development strategies . It is also an inevitable choice for the improvement of quality and efficiency of my country's construction. , the only way to transformation and upgrading.
3.1 Renewable resources development of building materials
At present, resource limitations have become more and more serious. As a country with only 1/4 of the world's per capita resources, the use of renewable resources to produce building materials has become the only choice for our country to develop new building materials. At present, the annual output of domestic waste and industrial waste in our country is staggering. Turning these wastes into treasures, recycling them for secondary use, and processing them into new building materials can not only reduce resource loss and environmental pollution, but also achieve environmental protection and ecology. and sustainable economic development. By making full use of recycled resources and adopting less-polluting production technology on the premise of ensuring product yield and reducing the loss of production raw materials, we can develop new building materials that are non-toxic, green, energy-saving, environmentally friendly and have good social benefits.
3.2 New smart materials development of building materials
Smart materials refer to materials that have self-diagnosis and damage prediction, self-regulation and repair, and can be reused. When the structure or load-bearing capacity of the material changes internally, the internal condition of the material can be displayed and self-adjusted [5]. New intelligent building materials are materials with new building functions that respond to and communicate with people through instructions given by people, allowing people to live in a more pleasant living environment. At present, this new type of intelligent building material has not yet become popular, but with the development of the construction industry and the progress of society, its application in building intelligence is imperative and is the development trend in the construction field.
3.3 Development of Environmentally Friendly Materials and Building Materials
As people's awareness of the living environment increases, people have higher and higher requirements for the economy, safety and comfort of the living environment. Traditional building materials still have some negative impacts on residents' lives and are difficult to meet residents' requirements, so they are gradually being eliminated. The relevant management departments of building materials should combine different regions and building types to promote the research and development and production of green and environmentally friendly building materials. At the same time, they should also strengthen cooperation among various departments, formulate and implement regulations on the application and management of new building materials, and solve the current problems of new environmentally friendly materials. Various issues in R&D and production applications to build an environmentally friendly building materials market.
3.4 Development of Composite Multifunctional Materials Building Materials
With the development of the national economy and the improvement of people's living standards, people are becoming more and more aware of architecture. Therefore, composite multifunctional building materials have emerged. Composite multi-functional building materials refer to the premise that they meet the main functions of building materials and have various other excellent properties at the same time. In the production process, new materials and new technologies are combined to integrate various advantages such as light weight and high strength, waterproof and moisture-proof, fire-resistant and high-temperature resistant, strong corrosion resistance, etc., coupled with microelectronic technology and high-tech technology, in terms of performance, use, and function. Make major breakthroughs in terms of safety and comfort, realize the regulation and improvement of modern buildings, and be more in line with world development trends and human life needs.
